A pneumatic tyre includes a tread portion, two axially spaced sidewall portions extending radially inwardly from the tread portion, at least one of the sidewall portions being provided with a side protector that protrudes axially outwardly and having an inner end located radially outwardly of a tyre-maximum-width position, and two axially spaced bead portions connected to radially inward of the respective sidewall portions. Each bead portion includes a bead apex rubber having an outer end in the tyre radial direction being located radially inwardly of the tyre-maximum-width position. A radial length of a tyre inner region from a bead baseline to the outer end of each bead apex rubber is in a range of from 0.8 to 1.2 times a radial length of a tyre outer region from a radially outermost position of the tread portion to the inner end of the side protector.

Tyre sidewall imaging method

A computer implemented method is proposed for classifying one or more embossed and/or engraved markings on a sidewall of a tyre into one or more classes comprising digital image data of the sidewall of the tyre. The method comprises generating a first image channel from a first portion of the digital image data relating to a corresponding first portion of the sidewall of the tyre. Generating the first image channel comprises performing histogram equalisation on the first portion of the digital image data to generate the first image channel. The method further comprises generating a first feature map using the first image channel and applying a first classifier to the first feature map to classify said embossed and/or engraved markings into one or more first classes.

A pneumatic tire has a large number of protector ribs on a side surface thereof. Each protector rib projects from a profile of the tire. The protector rib has an outer end and an inner end. A shape of a cross-section of the outer end is convex inward in an axial direction. The shape of the cross-section of the outer end is preferably a circular arc. A shape of a cross-section of the inner end is convex inward in the axial direction. The shape of the cross-section of the inner end is preferably a circular arc. The tire further has a lateral groove. An intersection angle of an axially outer end of this lateral groove relative to the profile is not less than 100° and not greater than 140°.
